,application Afiled January 2 lie, it l\;nown that l, t'rno M. (l'rx-n, a eilizeu ot thel United States, residing' ai the city ot .lalneatowiny in the county ot tlhantauqua and State ot New York, have invented certain new and nae't'nl Imprim-mentes in AMito-- mobile-Linups, ot which the following7 taken in connectioi'i with the. acconipanvingl drawings, is a specilication.

The invention relates lo lamps having parabolic reflectors; and the object ot' the improvement is to provide a sight -iuterccpti'ng multiple screedreflector constructed so as not to intercept the line ot light, except to a predeterulined ,pt 'oportion o'l the rays itor certain uses, the creen being proA vided with vspaced radial non-reflecting; blades which extend to within a short disstance of the lamp or source oli light so that said Source oil" light is screened from the sight oit' the bystauder or passer-by unless he is directly in line with the rayaI ot light, and tor antomobilc head lights` the npper-por tion is lnovidcd with a multiple tubular rev tlector which redirects the parallel reflected rays ot' light 'from the parabolic reflector downward so that none ot' the rays ot light from said headlight will risc above a predetermined level; and the invention consists in novel features and combinations hereinafter Set forth and claimed.

In the drawings, lliip'nre l is a t'ront ele vatiou ot' an automobile head light; aml Fig. 2 in a vertical eectiimal View at line 2--2 in Fig. 1 showirnr the innltiple tubular Screen-retlector in the upper portion and the radial blade sight.' interceptingr noinrcllecting Serien in the lower portion, the esectional view ahtnviinhT the control ot the rays ot' .light by dotted lines.

Fig', 13 is; an elevation ot the plate 'for intcrceliting the direct central ray ofthe light; and 'Fig'. 1-l iS ainclevation oit thel rear aide ot' said plate showing the, nia-nner of assembling the radial sight intercepting blades over spaced pins on said plate for a spot light. Fig. l5 shows the manner oi bending the double length radial sight utercepting bladenl from straight tlat. :stripe into V-shaped' radial blades, the. assembling block havingr spaced pins forholding said blades in spaced relation near their outer ends. Fig. lli is an elevation of a modification oi the pin method o'l` assembling the `adial blades showingsingle length radial blades but welded to a central ring.

Lilie characters oit reference refer to corresponding parts in the several views.

The numeral 2l) designates -a rellector 'lamp of either the headlight type or the spot lighttypc. 'The two types of lam )s 20 are each eonstrncltal with the para'ilbolic shaped outer casing); 2l which is. held in spaced relation to the parabolic Shaped reflector' 22 by the light post S23 at the center of on i the rellectqr 22 and casino 9,1 nml luv-the ont il t) nthe supporting rino "llie blades B3 may Wardly turner flange 2li around the outer rim ot the rollt-rotor E22 which flange 2l braces against the innerwall ofi the r'nn ot' the casing;- 2l thereby holding the outer rims ot both the parabolic reflector and the cas. ing 2l, tirinly in position. .A

fa zglass 2G is provided to cover the front of the retlector Q2, which glass held in place by the inclosing rim 9.7 attached to the casing 2l by the spaced screws 28. A. groove 2f) is provided in the outwardly turned tlangged rim ot the reflector 22 to receive therein a suitable packing 3() against which 3l tor the nniltiple tubular screenretleotor 3:. and radial blade sight intercepting screen rest. to thereby prevent all rattling as well as to inclose the in tcrior ont' the lamps Q0' against admission of dust and dirt. l

The rini also has a. 'groove 3l and pack-- ing therein which extend around said rim 'ot the visio-n screeirreilector and radial sight intercept-ing screen 38 tor the glass 2G to against so that all the parts .rnay be held lirn'ily in position in' their proper relation to one another by means of the rim Q?.

rlhe vision intercepting radial blade screen 3? consists of a series of spaced radial blades which extend from the center to the periphery oit the iront ot' the parabolic ren llector il?. or the spot light and trom the center of the lower habt to the periphery of `said -lower half ol: the headlight type of lamp. the upper "portion being filled with the multiple tabular screen reflector shown in my tornicr application or Letters latent Serial lio. 209903, filed (lan 2, 1918.

Each ol the blades are double the' length troia the periphery ot the screen to the center thereof, being bent crosswise at said center and lilshaped as shown in Figs. 9. l2

and il. This is preferably attained as shown in Fig. l5 in which a block 34E has the pins placed in semi-circular Jform and spared as desired fof-the outer ends ot onehalt of the screen. iv tool is then pressed against the middle of the plate 33 pushing sidowise until said blades 33 are assembled and bent into the lil-shaped 'orins shown in lfi 'l lt and in dotted outline in Fig. l5, ai' ti which a drop ot' solder on the contacting blades at the points 37 attaches them to one a nd can be removed from the block 3ft' and placed over the, pin 38 on thc central plate 'll. which plate 35i placed at the center ot the trent ot the screen in order to intercept the, central ray of lig-httroni the lainp or source of light Llll.

llach ot' the blades 33 extend inward as .shown at -ll around the lamp l0 so as to inx. is stamling;` directly in front ot' the saine. be made et thin' sheet :vu'io'ther so that the blades 'forni one piecev erwpt the sigrht trom the lamp unless 'one metal as shown in the automobile head light type 1n Figs. l and 2., which permits the direct light 'to freely shine upon the roadway. in front ot the lamp and also perniits a wide `angle extension ot the direct light in the spot .light type shown in Figs. 3 and al as indicated by the dotted line, the reflected light being; shown in parallel alineinent jfrom the parabolic reflector 22 and shining through the direct rays ot light.

l inodication or 'the method ot' attacl1- nient by means ot the pins 3S and Veshaped double. length blades 353, is shown in Fig. 1G, in which the blades 33 are made single length and butt Welded to a ring 42 which is attached to the inner side oft-he central blade 39. This arrangement will accomplish its purpose but is not as strong or as easily and cheaply accompished as the preferred method ot assenibing the blades 33.

The blades extend Jfrom the center to a. rim 3l which jireterably has the inturned lugs 44 struck from the sheet metal strip forming said rim 3l at the spaced intervals desired for the outer ends of the blades' 343 so that said outer ends may be spot Welded or otherwise attached to the lugs 4l. The rim 31 is shaped to attach wit-hin the reflector 22 having` Vthe out-turned grooved flange as hcrcinbetore described. l t extends around the inner periphery ot the ontcr portion ot the reflector 22 and supports the multiple screen-reflector 32 and screen 33 in the headlight type ot lamp or all of the blades B3 in the spot light type shown in Fifi.

For certain uses it is desirable to 'use only the parallel rays Ot reflected light as shown in lilies. LS for both the headlight and spot li grht tyjies of lamp. Accordingly, the blades 323 are provided with annular turned spaced lugs 45 which are struck from the blades 33 at spaced intervals sullicicnt to intercept all the direct rays ot light, the cent al rays being intcrceptedby the blade 23S). |The lugs l5 are graduated to extend between the spaced blades 3?, 'hirniing the complete circular or semi-circular ring;r according to the type of lamp, and thereby controlling the direct rays of light by paralleling or blocking out all rays" outside of the parallel reflected rays.
